GAS-LIGHTER.

Specification of Letters Patent.

Patented Oct, 1, 1919..

Application filed March 2, 1918. Serial No. 219,956.

To all whom it may concern:

Be it known that I, SAMUEL E. GUINN, a citizen of the United States ofAmerica, residing at Bowling Green, in the county of \Varren and State of Kentucky, have invented certain new and useful Improvements in Gas-Lighters, of which the following is a specification.

My invention relates to improvements in gas lighters designed primarily to be attached to the gas supply pipe of gas ranges, and adapted to be held in the hand to ignite a burner.

The invention aims to improve the construction disclosed in my pending application for patent Serial No. 146,440, filed Feb. 3, 1917, inthat the features are simplified, and the operation is rendered more convenient.

One of the principal objects of the invention is the provision of means arranged to ignite the gas by simply tapping the device on the range or other convenient place.

A further object of the invention is to provide means for simultaneously opening the gas valve at the time the operator, by movement of the hand taps the igniter:

The invention also comprehends improvements in the details of construction and arrangement of parts as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings Figure l is a perspective view of the igniter.

Fig. 2 is a longitudinal section of same.

1 indicates a handle, through which a pipe 2 passes, the pipe being extended beyond the ends of the handle, and is held in fixed relation by a screw 3, and a finishing nut 4. On the forward end of the pipe 2, is a gas chamber 5, considerably larger in diameter than the diameter of the pipe, and in the open end of the latter where it communicates through an opening 6 with the chamber.

Located adjacent the opening 6 and ex tending through a threaded sleeve on the gas chamber is a threaded stem 7, the outer end thereof having a head, which afiords convenient means for adjusting the stem.

In the sleeve is a coil spring 8, which bears against a sparking element 9, while the stem 7, engages the opposite end, the spring creating the necessary tension to force the sparking element forward.

Fastened to the handle is a resilient member 10, the forward end thereof being bent upwardly, as at 11, and passes through an opening formed in the wall of the gas chamber, and projects slightly therein. On the rear face of the bent up portion 11, is a friction plate 12, against which the sparking element resiliently bears.

Rotatable on the pipe 1, is a disk 13, formed with slots 14, through which headed pins 15, pass. The disk is formed with an opening 16, which is adapted to register'with an opening 17, in the handle, the opening 17, serving as a receptacle for additional sparking elements. By rotating the disk, the opening 16, may be brought into registry with the opening 17, for the insertion or removal of extra sparking elements, and by further movement of the disk the opening 17 can be closed to retain the elements for future use.

Mounted in the handle 1, and extending through thepipe, is a reciprocable valve 19 of any convenient type to control the passage of gas to the burner. The valve normally closes the pipe 2, and on its upper end is a thumb piece 20, located adjacent the inner end of the handle. The valve is retained in closed position by a spring 21. The valve shown is purely illustrative of but one form of valve, for it is evident any suitable valve structure which will serve the purpose can be employed.

In addition to the valve 19, a valve 22, is

1 attached to the free end of a flexible connection 25, or to the manifold of the gas range, to insure of the cutting off of the gas should the spring actuated valve fail to work.

In operation, the attachment is connected to the manifold of a gas range, and the valve 22 is turned on. The operator takes the handle in one hand, with the thumb on the thumb piece of the valve 19, then with a quick downward movement of the device toward the range the forward corner of the resilient member 10 taps the surface of the range, and friction element 12 is forced across the face of the sparking element 9, and generates a spark, at the time the operator moves the device to tap the resilient member, the thumb presses on the thumb piece 20 and opens the valve 19, consequently the spark generated ignites the gas, and the pressure of the latter ejects a flame from the front end of the gas chamber, and burner of the gas stove can be readily lighted. The flame will continue as long as pressure on the valve is retained, and as soon as such pressure is removed the spring 19 automatically closes the valve and the supply of gas is cut off, and of course the flame is. extinguished.

The gas chamber is of such diameter, with reference to the opening in the burner-tip, that the air contained in the chamber is to supply suflicient-mixture with the'gas toignite same When the spark is generated, hence it is not necessary to provide additional means for the: admission of airto'the chamher.

In connection with the ignition of. the gas when the; sparking deviceis operated, ithas been found that whenthe-frictionelement. is injected into; the chamber, i111 the path of the flowing gas, the latter is momentarily dissipated,or:pocketed between said element and the rear wall of the chamber. At this time the spark is generated,withthe result that the thin volume of gas in such. a large spacereadily mixes with the atmosphere in the 'chamber and quickly ignites. I. have found this decidedly advantageous and: .purposely. providethe frictional element of such tend-across the path of the flow of gasfron'i the pipe; and dissipate said gas between the element and the rear wall of the chamber, a handle mounted on the pipe in rear and spaced from the combustion chamber, and a flexible pipe connected to the rear end ofithe pipe tosupplygas to the pipe, whereby an operator can move the device within a given range and by tappingthefriction element to cause ignition of the gas.

2. A lighter comprising, a pipe, at combustion chamber on oneend of same, a handle on the pipe, a sparkingpelement-in the combustion chamber adap d to be operatedby the device against an o.bject,,and a valvel'o cated on the handle for openingtthepipe, saidvalvebeing positioned totbe engaged by the thumbof theoperator, whereby when the sparkingdeviceis tappedoni an object to createa spark the jart'will causeopenin'g of the valve for the passage of gas. s
